Just started using the Epson Perfection V600 on my MBP, OS X 10.10.3. Works as advertised except I have not the the, Event Button, manager. Event Button Manager (or something like that) is what you can program for the buttons located on the front of the scanner.

Yes. That is what this unit is designed for. The white media back under the lid slides off to reveal a backlight area 1/3 the width of the lid. The unit comes with an insert that holds 35mm film, 35mm slides and medium format film (like 4 x 5s) for scanning within the backlit area. The software allows for correction of dust and scratches when scanning.
